Android开发listView中的Button点击事件被拦截

根据http://blog.csdn.net/boylinux/article/details/8860443 这位大神的帖子，我的代码如下，现在的问题是Listview中的Button和imageview和textview控件点击之后不会响应，而在滑动一下Listview后，之前的点击事件才会响应，导致这个问题的原因不明，但是如果不用HashMap这个MAP的话，就不会有这个问题，请问大神们这是为什么呢？代码如下：
public class MyTwoAdapter extends BaseAdapter {
Context context;
private List data;
FollowInfo followInfo;
Bitmap bitmap;
FinalBitmap finalBitmap;
HashMap lmap = new HashMap();
private LayoutInflater mInflater=null;

public void setData(List<FollowInfo> data) {
    this.data = data;
}

public MyTwoAdapter(Context context) {
    this.context = context;
    mInflater = LayoutInflater.from(context);
    finalBitmap = FinalBitmap.create(context);//初始化FinalBitmap模块
    finalBitmap.configLoadingImage(R.drawable.ic_launcher);
}

@Override
public int getCount() {
    return data.size();
}

@Override
public FollowInfo getItem(int position) {
    return data.get(position);
}

@Override
public long getItemId(int position) {
    return position;
}

@SuppressLint("NewApi") @Override
public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder viewHolder = null;
    if (lmap.get(position)==null) {

// if (convertView == null) {
convertView = mInflater.inflate(R.layout.mytwo_item, null);
viewHolder = new ViewHolder();
viewHolder.user_logo = (ImageView) convertView.findViewById(R.id.user_logo);

    以下回答参考 皆我百晓生、券券喵儿 等免费微信小程序相关内容作答，并由本人整理回复。

    这个问题可能是因为在addListener方法中，您尝试在同一个OnClickListener中处理多个按钮（例如，no_up和yes_up），这可能导致在某个时间点上这些按钮已经处于不可用状态。为了解决这个问题，您可以考虑将每个按钮分别绑定到不同的OnClickListener。

    以下是一个修改后的版本：

    public class MyTwoAdapter extends BaseAdapter {

    Context context;
